Whether an organization is moving aggressively or cautiously into cloud-based services, the reality is that just about every enterprise will have a hybrid mix of services—including on-premise, private cloud, and public cloud—in place at any given time. As a result, an organization’s sensitive assets will often need to be transported across a wide area network (WAN) as data and processing are shared across these geographically distributed deployments. To build a trusted hybrid multi-site infrastructure, enterprises need to employ encryption to secure the transport of data across their WANs, while at the same time, ensuring high-speed and low-latency communications between these distributed sites.
